Where exactly can I find the potato? Think I've done everything I could, but I have yet to stumble on that potato for the achievement...

And while I did not encounter major bugs, for some reason I was able to give Warrick his armor while he was still in bed and I didn't earn the accolade. I'm planning to replay the game to get the stuff I missed the first time around, so when exactly am I supposed to give him his armor?

The potato is found in Galanor in the empty house~

As for the armor, you -are- supposed to return it to the closet before he wakes up for the accolade, so that's something we'll need to look at.
